LOCOMOTIVE ASH-PAN.

To all whom it 'may concern:

Be it known that I, ISAAC A. DAVIS, a citizen of the United States,residing at Grand Island, county of Hall, and State of Nebraska, haveinvented certain new and useful Improvements in Locomotive Ash- Pans, ofwhich the following is a specification.

This invention relates to locomotive ash ans. p The present inventionhas for its objects the provision of a novel ash pan adapted forquenching the ashes as they fall from the grate and collecting andretaining them for dumping when `desired by operation from the firemansdeck of the locomotive whether the engine be in motion or station aryand which will render it unnecessary for the fireman or helper to getunder the locomotive to effect cleaning or dumping of the pan.

The invention also has for its object the provision of an ash pan ofsuch novel construction that it is adapted for use in connection with alocomotive of any size or type by effecting minor adaptations andadjustments, and the disclosures hereinafter given in the specificationand in the drawings are to be deemed as illustrative, and notrestrictive, of the invention.

In carrying out the invention, there is provided a hopper adapted toinitially receive the ashes from the grate, together' with flooding orsprinkling means for quenching the ashes as they fall thereon, and anoscillating or rotary ash pan or re ceptacle into which the ashes passfrom the hopper, the receptacle or pan being arranged so that it willcatch the water and insure the quenching of the ashes, heating meansbeing preferably provided to keep the water in the pan from freezing incold weather and also anoverflow device so that the water will not slopover and by freezing impair the action of the pan. The pan is mounted ina novel manner for rocking or oscillating or, indeed, complete turning,so that its contents may be readily dumped at Aany time, new means beingprovided under the convenient control of the fireman on the firemansdeck for turning the pan to dump and restore it, but in its broaderaspect, the operating means may be varied and it may be either hand orpower operated and Specification of Letters Patent.

and lowering in a new manner so that when.

in raised receiving position it will be so disposed that the ashescannot accidentally fail to pass into the pan fromthe hopper and whenthe pan is to be dumped, it may be lowered for that purpose.

The foregoing statement of the invention is to be deemed as and for thepurpose of setting forth the structure and not in restriction of thescope of the invention.

In the accompanying drawings :-.-Figure 1 is a longitudinal sectionshowing the invention in use; Fig. 2, a detail view of the winding andlocking means for turning the ash pan; Fig. 3, an end elevation taken atthe left of Fig. 1; and Figs. i and 5, modifications.

The fire-box 1, grate 2 and drivers 3 are of ordinary construction. Theoscillating ash pan may be hung above or below the axle 4L, the latterbeing the construction shown.

Depending from the mud ring is a hopper or apron 5 whose ends and sidesslope and the lowermost central part thereof is made of troughsshape, asshown at G, to direct the ashes to the ash pan. Suitably disposedadjacent the hopper are one or more sprinkling or flooding water pipes 7which may run around the entire interior of the said hopper, and theyare provided with apertures or slots for directing the water on thehopper so that the ashes may be quenched prior to their passage into theash pan to insure the deadening of the ashes.

Depending from the front and rear ends of the hopper' 5 are hangers Shaving vertical slots 9 and notched at their lower ends 10.

Extending lengthwise of the locomotive between the hangers 8 is the ashpan 1l which has trunnions 12 passing through the slots 9 and adapted toboth turn and slide therein, said trunnions being supported by collars13 which constitute the bearings therefor, said collars being suspendedby chains or cables 14, from idlers 15 suitably journaled in the hangers8 and brackets connected thereto, the chains or cables thence passing toconnectors 16 of suitable construction on an elevating and loweringshaft 17 suitably journaled in hangers below the hopper 5 and extendinglongitudinally of the latter, the chains or cables being adapted to windupon the shaft 17 when it is turned to thereby take up or pay out thechains or cables 14 and bring about raising or lowering` of the ash pan,the shaft 17 being turned by means presently to be set forth.

The ash pan 11 is of substantially cylindrical construction, beingadapted to contain the water which flows from the pipes 7 and ispro-vided with a take-off or overflow 18 which prevents the water fromslopping over and thus obviates the formation of ice on the exterior ofthe parts which would interfere with proper operation in cold weather.For the purpose of preventing the water from freezing in the ash pan,there is provided a steam heating pipe 19 which enters the ash pan atone side of the hangers 8 and has its exit in a similar manner at theother end, said pipe passing to the lower part of the ash pan andlongitudinally thereof and being adapted for connection to a flexiblehose 20 on any suitable steam pipe, the hose permitting the ash pan tobe turned to effect dumping of its contents and restoration of the ashpan to normal position. The ash pan is open at its upper part 21 so thatit may telescope, as it were, over the depending part 6 of the hopper,and thus insure the entry of all of the ashes into said pan, and toprevent any accidental turning of the ash pan when in receivingpo-sition, there are provided the angle members 22 on the ash pan whichare adapted to engage with the notched ends 10 of the hangers 8, butwhen the chains or cables 14 are paid out, these parts clear each otherso that the ash pan may be turned.

Secured to one of the trunnions 12 is a sheave or pulley 23 to which at24 is connected a chain or cable 25 which passes around this sheave orpulley and thence around idlers 26 and 27, so that when the cable orchain 25 is pulled in one direction, the ash pan will be rocked to dump,and when pulled in the other direction, said ash pan will be restored tonormal position.

Different means may be employed for operating the chains or cables 14and 25, but for economy of space and certainty of operation, as Well asfor the sake of simplicity and durability, I preferably employ on thefiremans deck, at a suitable height and positioned for convenientoperation, a cage 28 of suitable form and strength in which the pulleys29 and v30 are mounted in separated arrangement on the same axis, thehubs 31 and 32 of the pulleys being, respectively, provided wit-hnotches 33 and 34, and mounted to slide lengthwise of these hubs is thestem or shaft 35 of a suitable handwheel 36, the shaft being providedwith one or more lugs or pins 37 which, according as the shaft 35 ispushed in or pulled out, will engage with the notch 33 or the notch 34,thus coupling one or the other of the pulleys to the said shaft so thatit may be operated by the hand-wheel. A cable or chain 14a which issecured to a sheave or pulley 38 on the shaft 17, is connected to one ofthe pulleys 29, 30. The cable 25 is passed around the other pulley andsecured thereto at 39. Gravity may be relied on to lower the ash pan asthe cable 14:L is paid out from the pulley to which it is connected, butfor purposes of dumping the ash pan, rocking it in its bearings orcollars 13, it is necessary to give it a positive pull in eachdirection. The pulleys 29, 30 may be locked in different ways to insureretention of the ash pan in raised .position and for this purpose teeth40 may be provided on said pulleys with which pawls 41 engage, which maybe released when it is desired to operatethe pulleys. A counterweightmay be utilized to cause dumping of the ash pan, as shown in Fig. 4, oran air or steam cylinder may be used for this purpose, as shown in Fig.5.

At 42 there is provided, preferably, a sight tube leading up through thefiremans deck through which he may observe t-he condition of the hopperand ash pan.

In my copending application, Serial No. 603,605, filed January 19, 1911,I have d isclosed another invention on a locomotive ash pan.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is
